Cute conifer, cold pot... it can work!
enlarge this imageIf you'll keep it out in a pot above ground over winter, choose for a plant hardy to a zone even colder than your own. Without earth stretching away on all sides -- the perfect insulation! -- many potted plants fail. Their roots freeze.
I have a dwarf Alberta spruce in a pot on my porch. I
love it. It's perfect. But I'm told it can't stay in the pot over
winter. Say it isn't so! - J.G. -
Picea glauca 'Conica' is a cutey -- a chubby Christmas
tree with cellulite problems. It's also long lasting in a pot -- we
know many that have been at their stations in a container for four
or more years. Thus, dwarf Alberta spruces decorate many
entryways.
Yours can stay in the pot over winter. It might die, but given
the staying power of evergreens, that fact wouldn't be of concern
until the plant browned out rather than greened up next May. Then,
start over with a new one. However, if a plant is too dear to risk
losing, you can insulate the pot where it sits or move it to a
protected spot.

winter, in ensemble

winter."
